When you lose a member of your family, everything is put on pause, including birthday parties.

While Coco and Ice-T had a birthday party planned for their only child, daughter Chanel Nicole, as she turned one this week, the reality star mom announced it was being put on hold in light of their beloved dog Spartacus' death.

"Cuz I've been mourning over Spartacus I put Chanel's Birthday on hold (which was today) I feel I need 2 honor Sparty before a celebration," she announced via Twitter late Monday.

She first revealed the family's loss on Sunday, explaining the dog had died from complications during knee surgery. "He was my 1st baby with Ice.There'll never be another," Coco wrote. "I feel his life was way too short. He touched everyone. I love u Spart."

Her husband of 14 years was equally heartbroken, taking to Twitter Sunday and Monday to air his grievances for his furry friend.

"I never knew I could feel so sad about something.. Thank you for ALL your kind words.. Spart was my guy! I'm F'd up. RIP Spartacus," Ice-T tweeted. "Spartacus was a Very special friend... You have no idea."

Even baby Chanel, who has thousands of Twitter followers, shared a sweet message on social media about her "big bro."

"I lost my big bro Spartacus today after knee surgery," a tweet from the infant's account read. "He was a cuddler & a lover. Had a short time w/ him but worth every minute of it."

The baby and her dog had developed an adorable bond, one chronicled by her famous parents on Instagram. In one recent shot of their daughter with Spartacus and fellow bulldog Maximus, Coco and Ice-T wrote, "Watching out for our little lady....."

In another of the infant sitting in between the two dogs, the caption read, "No one can mess with our little sis!"
